2017 Suzuki DR-Z400SM

Chassis Features

• Wide, blue-anodized RK Excel aluminum rims with stainless steel spokes are fitted with high-grip sportbike radial tires: 120/70-R17 front & 140/70-R17 rear
• Strong braking performance is supplied by a front disc brake with a large 300 mm floating-type rotor and dual-piston caliper, plus a 240 mm rear disc brake with single-piston caliper
• Long travel, SHOWA inverted front fork is derived from a RM250 and features adjustable compression / rebound damping and alumite coating on inner tube surfaces for smooth action
• A fully adjustable rear shock absorber with high / low speed compression damping adjuster and a tapered RM-inspired aluminum swingarm combine for precise rear wheel control
• Renthal tapered aluminum handlebar has an aggressive look, reduces vibration and has a great bend for spirited riding
• Chrome-moly steel frame tuned for Supermoto style riding is torsionally strong with minimal weight. The backbone tube, front down tube, and steering head gussets form the dry-sump engine oil tank
• A bolt-on aluminum sub-frame helps reduce weight, simplify maintenance and contributes to the trim rear fender appearance
• Front and rear axle sliders help protect against damage in the case of a tip-over

Electrical Features

• Compact digital instrument cluster with speedometer, odometer, and twin-trip meters with addition / subtraction capability, clock and stopwatch functions

Engine Features

• Lightweight 398 cc, DOHC, liquid-cooled, dry-sump engine produces strong, tractable power

• Simple electric starting via a lightweight starter motor with an automatic mechanical decompression system
• SCEM-plated cylinder (nickel-silicon-phosphorous) is lighter and more durable than an iron liner with excellent heat transfer properties
• Forged aluminum piston is 10 percent lighter than a cast piston and receives additional oil-cooling to the piston crown through a crankcase oil jet
